Science: Gravity & Magnetism

A challenging item in the unfinished business of science is to find some
connection between magnetism and gravitation. The universe is shot
through & through with electromagnetism; gravitation is everywhere too.
Physicists have long been convinced that the two must be related
somehow, but try as they would (and the most talented have tried), they
could establish no basic connecting law.

Last fortnight Britain's famed, curly-haired Professor Patrick Maynard
Stuart Blackett of Manchester University told the Royal Society how the
